"I saved letters from my boss. There are things in there that are directly transcribed. I was so glad I did that. Sometimes when I was writing the book I wondered if some little writer hobbit part of my brain was back there puppeteering that action. But it really never, on any conscious level, occurred to me that I would write about it. I will say, I thought probably some day there would be an ancillary character in some novel - not in the one I was currently writing - that would be a dominatrix or something."
